Integrated rating for 600 ampere HVL/cc switches with Square D
® DIN/E fuses listed below is 65 kA rms symmetrical amperes. (50 kA rms for 630 ampere fuse.)
Current-limiting fuses increase the integrated short-circuit current rating because of their energy-limiting capabilities.
To increase the short-circuit current rating of the entire lineup of switchgear, current-limiting fuses must be used in the entrance sections.
